Hi Jan,

thanks for testing it!

>Like what for example? I don't want to kill something important.

I'd start a new process, for example:

cat &

then note the process ID (on the right; if it's not shown, invoke jobs -p).

Also, could you try the attached version of /etc/init.d/guix-daemon ?

Thanks!
